Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
190 words
Glide missile including a missile body having a longitudinal axis, said missile body having a forward end and trailing end and trim means mounted on said missile body for generating a positive angle of incidence of said missile body, wherein the improvement comprises a missile tip rotatably mounted on the forward end of said missile body, said trim means located in said missile tip, means associated with said trim means for receiving ram air in said missile tip and controlling the flow of the ram air through said trim means for adjustably positioning said trim means, said ram air control means comprising a fluidic element arranged to receive ram air and having an inlet opening in said missile tip and facing in the forward direction of said missile body, said fluidic element including a pair of outlets and a pair of control lines with each said control line associated with a different one of said outlets and means associated with said pair of control lines for opening one of said outlets and closing the other one of said outlets for controlling the flow of ram air through said trim means.
Claim 2
Dependent Claim
190 words
Glide missile including a missile body having a longitudinal axis, said missile body having a forward end and trailing end and trim means mounted on said missile body for generating a positive angle of incidence of said missile body, wherein the improvement comprises a missile tip rotatably mounted on the forward end of said missile body, said trim means located in said missile tip, means associated with said trim means for receiving ram air in said missile tip and controlling the flow of the ram air through said trim means for adjustably positioning said trim means, said ram air control means comprising a fluidic element arranged to receive ram air and having an inlet opening in said missile tip and facing in the forward direction of said missile body, said fluidic element including a pair of outlets and a pair of control lines with each said control line associated with a different one of said outlets and means associated with said pair of control lines for opening one of said outlets and closing the other one of said outlets for controlling the flow of ram air through said trim means.
Claim 3
Dependent Claim
21 words
Glide missile, as set forth in claim 1, wherein said ram air control means being arranged for roll-stabilizing said trim means.
Claim 4
Dependent Claim
75 words
Glide missile, as set forth in claim 2, wherein said fluidic element comprises a bistable fluidic element said pair of outlets from said fluidic element located in angularly spaced apart relation about the longitudinal axis of said missile body in said trim means, a shutter located in said missile body, a gyroscope mounted in said missile body for controlling said shutter, said control lines connected to said shutter for selectively controlling flow from said outlets.
Claim 5
Dependent Claim
17 words
Glide missile, as set forth in claim 1, wherein said trim means comprises a pair of fins.
Claim 6
Dependent Claim
58 words
Glide missile, as set forth in claim 4, wherein said fins are symmetrically angularly spaced apart on said missile tip relative to the longitudinal axis of said missile body, and each of said outlet lines being associated with a different one of said fins and opening from the trailing side of said fin with which it is associated.
Claim 7
Dependent Claim
40 words
Glide missile, as set forth in claim 4, wherein said fins are symmetrically angularly spaced apart on said missile cone relative to the longitudinal axis of said missile body and the angle of incidence of said fins being separately adjustable.
Claim 8
Dependent Claim
30 words
Glide missile, as set forth in claim 6, wherein the angle of incidence of said fins being equally adjustable in dependence on the magnitude of pressure of the ram air.
Claim 9
Dependent Claim
22 words
Glide missile, as set forth in claim 4, wherein said trim means comprise controllable spoilers located in the region of said fins.
Claim 10
Dependent Claim
18 words
Glide missile, as set forth in claim 5, wherein said fins are rigidly connected to said missile tip.
Claim 11
Dependent Claim
29 words
Glide missile, as set forth in claim 5, wherein the axis of said fins mounted on said missile cone extends transversely on the longitudinal axis of said missile body.
Claim 12
Dependent Claim
31 words
Glide missile, as set forth in claim 5, wherein said fins are movably connected to said missile body about an axis extending perpendicularly of the longitudinal axis of said missile body.
